Application lfiled. May 25, 1908. Serial No. 434,720.

To all whom it 'may concern:

Be it known that '1, HARRY E. KAY, a citizen of the United States, residing at East.

Templeton, in the county of Worcester and' State .of Massachusetts, have invented a new and useful Turbine-Motor, of which the following is a specification. v

This invention relates to amotor which,

while capable of operation by Iiieans of,

other sources of power, is especially designed as a water motor.

The principal objects .of the invention are to provide for getting a much higher eiliciency from a source of power than has been done heetofore with turbine wheels. In order Vto accomplish thisresult, two series of Wheels are employed, arranged alternately and facing in opposite directions, so t-liat the water discharged from one wheel will enter the next one at such an angle that it will act upon it with full force. A number of these wheels are arranged in such a way that those facing in one-direction rotate a shaft, and thosel facing in the other direction rotate a secondshaft the other way. Means is provided whereby the shafts and wheels are conveniently located to receive and transmit a maximum amount of power.

Further objects and advantages of the inventionwill appearhereinafter.

Reference is to be had to the accompanying drawing, in which-- Figure 1 is a longitudinal central sectional view of a water motor constructed according to this invention, Fig. 2 is a similar view on anenlarged scale showing a detail, and Fig. 3 is a fragmentary elevation of a detail.

The device is shown -as comprising a casing 10 having an in-take 11. The in-take discharges into a chamber 13 which is connected by a longitudinal cylindrical passage llt'with'the outlet 15. The passage may conveniently be horizontal as shown. The casing is provided with two bearings 16 and 17 at o posite ends thereof and preferably in axia alinement. In these bearinds are arranged shafts 18v and 19. Each of3 these shafts is supported outside the casing by inde endentbearings 20, and each carries a pulley 21 or other device by which power may be transmitted from them. Two sets of turbine wheels 22 and 23 are employed facing in opposite directions, and are arranged alternately. All the wheels 22 are fixed to the shaft 18 while the wheels 23 have openings 24 therethrough through vwhich the shaft 18 passes freely.A Arranged outside of all the wheels is a cylindrical casing 25 fixed to the wheels 23, and in which the wheels 22 freely rotate. The last Wheel 23 which is fixed to the casing 25 is also Fixed to a hub 26 secured to the end of the shaft 19. As the shafts 18 and 19 rotate in opposite directions the hub 26 is extended to form a bearing for the end of the shaft l18 and the two shafts are spaced apart a short distance to forni a chamber 27 in which an anti-friction ball-bearing 2S is placed.

I am aware that two turbine wheels have heretofore been placed to rotate inopposite directions, and connected up with the driving mechanism in various ways, but by means of this invention the number of driving wheels can be increased indefinitely so that such number may be em loyed as is found most. eiicient for the hea or the other conditions which may be present in each case. It will beunderstood, of course, that the addition of pairs of wheels will increase the eiiciency up to a certain point and beyond that the use of more wheels will practically not give further increasein power.

The operation of the device will readily be understood, the water entering the wheel 22 at the left turns it in the direction of the arrow, and is discharged in such a direction that it will have its greatest efficiency to turn the next Wheel 23 1n the other direction so that the shaft 18 and casing 25 will rotate oppositely. The water discliai ed from the first wheel 23 will enter the w ieel 22 so as efiiciently to operate it. A number of wheels should be chosen so that the water discharged from the last one will have practically no velocity, theentire head having been employed in the course of the passage of the Water through the casino to rotate the several wheels therein. It will be seen also that the shafts 18 and 19 and the casing 25 are arranged in a. very practicable manner 011 account of the locations and arrangement of the bearing, and of the passage 11 and containing the same. This is preferably connected on the end of the shaft 19, as indicated 1n- Fig. 3. The shaft 18 is also provided with passages 33by which the lubricant can pass to the bearings of the wheels 23. Thus these bearings, as well as the antifriction bearings are thoroughly lubricated from a readily accessible point.

While I have illustrated and described a preferred embodiment of the invention and a. certain number of pairs of turbine wheels, and while I have illustrated the invention as employed for operation by a head of water, I am aware that the invention may be carried out in many other ways, and that many modifications may be made without departing from the scope thereof as expressed in `the claims. Therefore, I do not wish to be yshafts in longitudinal alineinent extending into the casing from opposite ends, a series of turbine wheels in the passage, all facing inthe same direction, a second series oflturbine wheels in the passage, all facing in the other direction, and located and arranged to rotate independently of the first ser1es^of wheels, and a rotary casing in said passage surrounding all of saidwheels andfixed to the secondvset thereof, one set of wheels being xed to one of the shafts, and the rotary casing to the other.

2. In a turbine motor, the combination of a. plurality of turbine wheels arranged axially in alinement, each alternate wheel facing oppositely from the others, a shaft pass.-

ing through said wheels to which all the .45

wheels facing in one direction are fixed, a casing surrounding the wheels to which all the remainder of the wheels are fixed, a second shaft in line with the rst shaft and secured to said casing, anti-friction bearings between the'ends of said shafts, and means for directing a stream through all of `said wheels in succession inside the casing, whereby the shafts will be rotated in opposite directions. y v

3. In a turbine motor, the combination of two shafts arranged end to end, a hub fixed to the end of one shaft and projecting over the end of the other and forming a bearino therefor, anti-friction bearings/1n said hu between the shafts, means for supporting the opposite ends of the shafts, and two series of turbine wheels one' fixed to Yone shaft and the other connected with the other.

4. In a water motor, the combination of a casing'having an in-take, a chamber at the end of the in-take, an 'outlet and a horizontal passa fre connecting said chamber with the outlet, said casing also having two bearings in alinement beyond the ends of said passage, a pair of shafts each'extending into the said casing through one of said bea-rings, independent bearings outside the casing for supporting said shafts, a series of turbine wheels all facing in the same direct-ion and fixed on one of said shafts, a second series of turbine wheels all facing in the other direction and located to rotate independently of the shaft on which the other wheels are fixed, and a casing surrounding all of said wheels and fixed vto the seconds'et thereof, said casino` being secured to the shaft to which the first set of wheels are not fixed.

5. Inv a turbine mot-or, the combination of two shafts arranged end to end, a hub fixed to the end of one shaft and projecting over the end of the other and forming a bearing therefor, anti-friction bearings in said vhub between the shaft-s, means for supporting the opposite ends of the shafts, two series of turbine wheels one fixed to one shaft and the other connected with the other, said shafts having passage therethrough extending to `said anti4friction bearings.

6. In a motor, the combination of two shafts arranged end toend, turbine wheels for turning said shafts in opposite directions, an anti-friction bearing between the ends of the shafts, a hub on one shaft forming a bearing for the end of the other and providing a casing for said bearing, said shafts having longitudinal passages, and

means for supplying a lubricant through one of said `passages tothe anti-friction, bearing land to the yother shaft.

7 -In a motor, the combination vof two shafts arranged end to end, turbine wheels for Vturning said shafts in opposite directions,

a bearing between the ends of the shafts, a hub on one shaft forming a bearing for the end of the other and roviding a casing for said bearing, said sha ts havino' longitudinal passages, and mea-ns for suppying a lubricant through one of said passages to the.

bearing andv to the other shaft.

In testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.
